is not a difficult course. But it is quite a lot of memorization.
Essentially you are memorizing the greek and latin root words, prefixes, and suffixes for a large amount of the parts/regions in the body.
When I took it, every week was a different system and every Friday a different quiz with an exam every 3 weeks.
My favorite word I learned in there: encephalomyelomeningitis. It means your brain, your spinal cord, and your meninges are experiencing inflammation. Your entire nervous system is pretty much in distress.
Index cards will be your friend. Get 3-4 packs of them and carry them everywhere you go.
Good luck, you will do fine.
